2. Presentation of HDM-Sentry
For potential users of the HDM-4 software there are often barriers
to its use; HDM-Sentry aims to provide a simplified introduction to
a HDM-4 analysis to demonstrate its use.
This presentation will give an overview of HDM-Sentry and who it
is aimed at, together with a video of HDM-Sentry in use.

3. Introduction to HDM-Sentry
• There are often a number of perceived hurdles preventing new users
from adopting HDM-4 despite its international acceptance and
popularity, especially in countries with limited resources.
• These can be listed as:
• HDM-4 is “data hungry” and in many countries data is scarce.
• HDM-4 is a complex tool and requires a long learning curve before an
effective analysis can be produced.
• The development of a high-level simplified HDM-4 interface will
address both of these issues

4. Introduction to HDM-Sentry
• HDM-4 Simplified Entry – HDM-Sentry
• Aims to guide the user through the process of performing an analysis enabling
them to get some results with minimal training
• Will only require the user to supply minimal data by utilising the concepts of
Information Quality Levels (IQL), sensitivity analysis, and default data
• Key results will be presented to the user in a form easy to understand
• The analysis is performed using the full HDM-4 analysis framework and
standard models allowing a user to progress to utilising the full power and
customisation of HDM-4 as their knowledge, skill, and data improves

5. HDM-Sentry
• HDM-Sentry is a tool for:
• Performing an analysis of a road section to determine the economic and
engineering benefits of different maintenance and improvement investments
• Reducing data requirements by using high-level text descriptors for many of
the inputs which are automatically translated into the detailed data used for
the analysis
• Providing an accessible analysis method to decision makers, non-engineers
and those with no HDM-4 experience but still using the full HDM-4 analysis
framework and models to provide robust results

6. HDM-Sentry
• Interface for simplified data entry into HDM-4
• Four simple data entry screens guide the user through the setup process
• Automatically creates HDM-4 workspace based on user’s data choices
• Runs HDM-4 analysis in the background
• Presents the key results in an easy to understand format

8. Who is HDM-Sentry for?
• Decision makers, and non-engineers: using guided input and high-
level data entry detailed engineering knowledge is not required to
perform an analysis to obtain some indicative results on the impact of
different investment strategies
• Engineers with little or no HDM-4 experience: a low learning-curve
quickly enables engineers to set up an analysis and become familiar
with the process providing a stepping-stone to HDM-4 use.
• Educators: provides a quick and easy way to demonstrate the
principles behind economic evaluation of road investments.

9. Example HDM-Sentry Usage
• Problem Outline: A section of road is constructed using gravel
material and requires frequent maintenance to keep it in good
condition. Its traffic levels are currently low, and are predicted to
grow slowly over time. The road agency are considering an improved
maintenance policy, or reconstructing the road to a bituminous road
to reduce the frequent annual maintenance requirement.
• Can this be economically justified?

21. What next?
• The user can quickly change key inputs to determine the effect on the
results, for instance, What would happen to the benefits if my traffic
growth was ‘High’?
• The indicative results can be used to justify the need for a more
detailed analysis to be performed within HDM-4 to develop a case
study for funding. The HDM-Sentry analysis can be used as the
starting point for this analysis.

22. Advanced – View and optimise analysis in HDM-4 Version 2

23. HDM-Sentry In Use
• Multiple analyses can be stored to be viewed and edited when
required
• The three official languages of PIARC are supported: English, French,
and Spanish
• Local currencies can be added for reporting
• Customised datasets can be developed to support local high level
data customisation
